[Andrew Morton]

The quilt patch titled
     Subject: mm/damon/paddr: support only damos->ops_filters
has been removed from the -mm tree.  Its filename was
     mm-damon-paddr-support-only-damos-ops_filters.patch

This patch was dropped because it was merged into the mm-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Subject: mm/damon/paddr: support only damos->ops_filters
Date: Tue, 4 Mar 2025 13:19:09 -0800

DAMON physical address space operation set implementation (paddr) started
handling both damos->filters and damos->ops_filters to avoid breakage
during the change for the ->ops_filters setup.  Now the change is done, so
paddr's support of ->filters is only a waste that can safely be dropped. 
Remove it.
